Is Costco (COST) Stock Halal? Shariah Compliance Analysis
Costco is a membership warehouse retailer. Its annual report names liquor and tobacco and does not say how much of its sales they are, so COST screens Doubtful.

Overview of Costco's Business
Costco Wholesale Corporation operates a chain of membership-only warehouse clubs selling a wide selection of merchandise at bulk prices. The company offers groceries, electronics, clothing, household goods, and services including pharmacy, optical, and fuel stations. Costco generates revenue from merchandise sales and annual membership fees. The company is known for its limited product selection at consistently low prices.
Business Activity Screening (Qualitative)
Costco's main trade is warehouse retail: food, household goods, electronics, plus membership fees. That is a permissible business, so Costco does not fail at the first question the way a brewer or a conventional bank does. The difficulty is on the shelf. Costco's annual report for fiscal 2025 lists liquor and tobacco inside its Foods and Sundries category. It puts no figure on either. For a company whose main trade is permissible, AAOIFI Shari'a Standard No. 21 tolerates impermissible income under 5% of revenue. That test needs a number, and the filing does not give one.

Financial Ratio Screening (Quantitative)
The two money limits are separate from the shelf question. Interest-bearing debt has to stay under 30% of market capitalization, and interest-bearing deposits and securities under 30%. When this post was last updated, Costco was inside both limits. Those ratios are measured against the share price, so they can move without Costco borrowing a dollar more. We do not print the figures here because they would go stale. The COST stock page carries the current numbers. The third test, impermissible income under 5% of revenue, is the one that cannot be settled, for the reason above.
What Muslim Investors Should Consider
As of September 2026, HalalScreener's screen rates Costco Doubtful. The reason is simple: the filing confirms that liquor and tobacco are sold and does not say how much. Two shortcuts are tempting. One is to assume the worst and mark the stock Not Halal. The other is to assume the share is small and pass it. We take neither, because both put a number on the page that Costco never gave. A share we cannot measure is not a share we can call small. Doubtful is not a quiet yes. Many investors simply leave doubtful holdings alone, and caution with doubtful matters is taught in both the Sunni and the Ja'fari traditions. If you already own Costco, take the question to your own scholar, and those who follow a marja' should refer it to their marja'. Purification is for the small impermissible share inside a holding that passes the screen. It does not settle a Doubtful verdict. And the verdict can move: an annual report that states the liquor and tobacco share would settle it one way or the other. We screen, we do not certify.
